' IMPROVEMENT IN `'SEIT'ITIEi FOR LOOMS.

The Schedule referred to in these Lettera Patent and making part ofthe same.

and State of Massachusetts, have inverted certain new and 'useful.inprovements in Shuttles for Looms, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, inaking part of vthis specification, in which- Figure 1 represents, in part, a side elevation of an ordinary shuttle, at oneendof which is shown, in section,.cen trally and longitudinally, the wood portion A, the tip B, andthe'shank C of the tip.

Figure 2 is; a vertical elevation of the tip and shank, showing the method of uniting the saine, and of removing said tip, whenever such `removal becomes necessary.

Qui' invention relates to the tip of a shuttle, and has for its object to facilitate the application of the tip Ato the ends of the shuttle-woods, while the shank isvxed therein, and to furnish laineans for producing a cheap and serviceable device, for the above-indicated purpose, which will admit of itsbeing furnished with a new tip, withoutv injury to the other parts of the shuttle, vby withdrawing the shank oin the wood, thus endangering the splitting of the same, and-necessitaing a newshank, as well as its tip.` l

In constructing and applying our invention, the tip B is formed and iinished in any of the usual ways, but the shank C is iirst made square, in its transverse seetion, and then twisted, as seen in the drawings, lthe square corners forming a long, shallow-,threaded screw,

vcapable of being driven into a hole 'in the end of the wood of which the shuttle is formed.

The sharp corners of the twisted shank, instead of acting like a wedge, to split the -wood, cut their way spirally in the sides of the hole, thus securing themselves therein, without, to any great extent, endangering the splitting oi' the wood.

Fig 1 of the drawing shows-ashuttle, A, with its tip secured thereto, in accordance with our invention.

Fig. 2 showsthat the shank isA preparedfor the receptionw of the tip, by having a screw cut upon a reduced portion thereof, at the end which is to enter lthe tip, and that a corresponding screw is cut vwithin a.

hole. formed in such tip, for the receptionof the shank. The tip B may be made of any suitable metal, such as'steel, case-hardened wrought-iron, or cast-iron, and, as is apparent, it maybe removed at any time, for. the purpose of being repaired, and for the purpose of applying a new one, when the original one becomes' worn or brokeln Having thus described our invention, What we claim, and desire to. secure by 4Letters Patent, vis

The twisted shank C, provided with the removable tip B, constructed substantially as shown and described, in coinbinationwith a shuttle.
